How would YOU improve the Deathstrike?

As the title says, how would you improve the Deathstrike? I think it should have the "torrent" "devastating wounds" and "ignores cover" rules. Shouldn't have to worry about ballistic skill and the possibility of the enemy having a cover save. But to get around the blast rule it could have 2d6 + 6 attacks and do 2 damage instead of 1. What do you think? What would you change it to?
